CMS: LiDAR Data for Forested Sites on Borneo Island, Kalimantan, Indonesia, 2014

This dataset provides airborne LiDAR data collected over 90 sites totaling approximately 100,000 hectares of forested land in Kalimantan, Indonesia on the island of Borneo in late 2014. The data were collected as part of an effort to establish a national forest monitoring system for Indonesia that uses a combination of remote sensing and ground-based forest carbon inventory approaches.

This dataset contains 409 data files in LiDAR (*.laz) file format and one compressed shapefile (*.zip) providing the LiDAR file footprints. Note that derived data products including digital terrain models, digital surface models, and canopy height models are provided in a related dataset.

Project: Carbon Monitoring System (CMS)

The NASA Carbon Monitoring System is designed to make significant contributions in characterizing, quantifying, understanding, and predicting the evolution of global carbon sources and sinks through improved monitoring of carbon stocks and fluxes. The System will use the full range of NASA satellite observations and modeling/analysis capabilities to establish the accuracy, quantitative uncertainties, and utility of products for supporting national and international policy, regulatory, and management activities. CMS will maintain a global emphasis while providing finer scale regional information, utilizing space-based and surface-based data and will rapidly initiate generation and distribution of products both for user evaluation and to inform near-term policy development and planning.

siteid    = three-digit site identifier (corresponds to siteID attribute in indonesia_lidar_footprints.shp)

zone     = UTM Zone

section = Number differentiating sub-unit within each survey site

The data were collected as part of an effort to establish a national forest monitoring system for Indonesia. Future goals of the project include mapping forest carbon stocks across Kalimantan and estimating forest carbon flux associated with logging. 

Uncertainty associated with this data has not been analyzed. 

This dataset was produced as part of an effort to establish a national forest monitoring system for Indonesia that uses a combination of remote sensing and ground-based forest carbon inventory approaches. The effort was led by Applied GeoSolutions (http://www.appliedgeosolutions.com/) and funded through NASA's Carbon Monitoring System project with support from Winrock (https://www.winrock.org/), NASA's Jet Propulsion Laboratory, the University of New Hampshire, Wageningen University, and the University of Virginia.

Data Acquisition

Airborne LiDAR observations were collected over 104,000 hectares of forest across Kalimantan, Indonesia on the island of Borneo between 18 October and 30 November 2014 by Jakarta-based company Surtech (http://www.surtech-group.com/). The data were collected at point densities ranging between 4- and 10-ppm. 

The raw LiDAR observations were used to generate additional data products including digital terrain models, digital surface models, and canopy height models for each of the 90 survey sites. These data are provided in a related dataset:
